100% accurate, and I say this as a full Hara supporter who's seen her many times since my first review (always leave wondering, why do I roll the dice on so many okay experiences when Hara is so consistently good, but I digress). Hara deserves a great reputation for being so completely and consistently devoted to pleasing, but DT is inaccurate.
Based on the usage of "DT" in many reviews I've read over the years, I feel like some guys define it as just taking a dick all the way to the back of your mouth, which is just... a good deep blowjob. But that's not DT.
